Given numbers are 450, 680, 445, 407

The list of prime factors of all numbers are

Prime factors of 450 are 2 x 3 x 3 x 5 x 5

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 445 are 5 x 89

Prime factors of 407 are 11 x 37

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 450, 680, 445, 407

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(450, 680) = 30600

GCD(450, 680) = ( 450 x 680 ) / 30600

= 450 / 680

= 450

Step2:

LCM(10, 445) = 890

GCD(10, 445) = ( 10 x 445 ) / 890

= 10 / 445

= 10

Step3:

LCM(5, 407) = 2035

GCD(5, 407) = ( 5 x 407 ) / 2035

= 5 / 407

= 5

So, Greatest Common Divisor of 450, 680, 445, 407 is 1
